无法安装模块，无法分配内存错误?

问题描述

我刚刚启动了一个新的EC2 ubuntu t1.micro.我安装了R 3.1.2，当我尝试安装任何模块时，我得到了:

I just launched a new EC2 ubuntu t1.micro. I installed R 3.1.2 and when I try to install any module I get:

Warning messages:
1: In system2(cmd0, args, env = env, stdout = outfile, stderr = outfile) :
  system call failed: Cannot allocate memory
2: In install.packages("zoo") :
  installation of package ‘zoo’ had non-zero exit status

我阅读了另一个问题这可能是因为交换内存，但是在我的情况下，该内存设置为60，我认为应该没问题.

I read on another question that this might be because of the swap memory, but in my case the memory is set to 60 which I think should be all right.

当我运行.libsPaths()时，我会得到

> .libPaths()
[1] "/usr/local/lib/R/site-library" "/usr/lib/R/site-library"
[3] "/usr/lib/R/library"

起初，R抱怨它没有在/usr/lib/R/library上进行写操作的权限，但是当我更改目录权限后，该错误消失了.

At first R was complaining that it did not had permission to write on /usr/lib/R/library, but after I changed the directory permissions that error went away.

任何有关如何使其正常工作的线索将不胜感激.谢谢

Any clue on how to get it to work will be appreciated.Thanks

推荐答案

因此，我测试了在更大(t1.small)实例下执行的操作完全相同，并且工作正常.看来R在EC2 t1.micro实例上不能很好地发挥作用.

So I tested doing the exact same under a bigger (t1.small) instance and it worked fine. It looks like R does not play good with EC2 t1.micro instances.

这两种类型的实例之间的主要区别在于，尽管t1.micro具有0.6GB的内存，而t1.small具有1.7GB.

The main difference between those 2 types of instances is that while the t1.micro has 0.6GB memory the t1.small has 1.7GB.

无法在t2类型实例下对其进行测试，它们的性能可能会更好.

Couldn't test it under t2 type instances, they might perform better.
